With the development of science and technology, the structural characteristics of the bogie are changed continuously, and the conventional bogie has various types, wherein the cross-support bogie has the advantages of simple structure, firmness, good load balancing property and the like, and is mainly used by the conventional freight car, such as a rotary K1Steering frame, steering K2Steering frame and steering K6A type bogie, etc. Because the cross-bracing bogie is a large-scale component produced in large scale, when the manufacturing tolerance of each part is too large, the performance parameters of the bogie often generate larger discreteness due to the accumulated tolerance of each part after the bogie is formed, and the performance of the bogie is not kept and improved. Therefore, in order to ensure excellent and stable running performance of the cross-bracing bogie, it is generally necessary to check various dimensions such as height dimension of a spring bearing platform of a side frame of the bogie from a top surface of a pedestal during production of the cross-bracing bogie.
In the prior art, some technical documents measure relevant dimensions of a side frame of a bogie, such as height dimension of a spring bearing platform surface of the side frame of the bogie from a top surface of a guide frame by a platform scribing technology, that is, the top surface of the guide frame of the side frame of the bogie is erected by equal-height cushion blocks to serve as a reference surface, and a height difference between the spring bearing platform surface and the top surface of the guide frame is measured by a scribing needle to be the space dimension. However, the method has low efficiency, and in order to ensure the smooth production and assembly of the bogie, the dimension measurement of the side frame of the bogie can be realized only by a sampling inspection mode, the reliability of all bogies cannot be ensured, and the measurement precision of manual marking is not high, so that the accumulated tolerance of the assembly of each part of the bogie is larger, and the stability of the bogie is not favorably improved.
In other technical documents, a special measuring tool for measuring the distance between the top surface of the guide frame of the side frame of the bogie and the spring bearing platform is prepared, a bracket assembly is placed on the spring bearing platform of the side frame of the bogie, a measuring tool frame assembly is arranged on the bracket, and the whole measuring tool frame assembly is driven to move through the up-and-down movement of a steel pipe in the bracket assembly, so that the measuring tool frame assembly is lapped on the positioning bearing platform of the bearing saddle of the guide frame of the side frame of the bogie and contacts with the top surface of the guide frame, and the distance between the top surface of the guide frame and the spring bearing platform is measured. In addition, in the process of measuring and reading, the balance of the gauge frame assembly needs to be kept all the time, namely, the leveling step after the steel pipe in the bracket assembly moves is also involved, so that at least one side of the positioning circular muscles on two sides in the gauge frame assembly is in contact with the side frame spring bearing platform, and the distance between the other side of the positioning circular muscles and the side frame spring bearing platform is not more than 1.5 mm. Therefore, the device is used for measuring the distance from the top surface of the guide frame to the spring bearing platform, so that the operation flexibility is not enough, the operation steps are complex, and the measurement efficiency is low.
